DETAILED DESCRIPTION

The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present disclosure.

Parts that are irrelevant to the description will be omitted to clearly describe the present disclosure, and like reference numerals designate like elements throughout the specification.

Further, in the drawings, the size and thickness of each element are arbitrarily illustrated for ease of description, and the present disclosure is not necessarily limited to those illustrated in the drawings. In the drawings, the thicknesses of layers, films, panels, areas, regions, etc., are exaggerated for clarity. In the drawings, for ease of description, the thicknesses of some layers and areas are exaggerated.

It will be understood that when an element such as a layer, film, region, or substrate is referred to as being “on” another element, it can be directly on the other element or intervening elements may also be present. In contrast, when an element is referred to as being “directly on” another element, there are no intervening elements present. Further, in the specification, the word “on” or “above” means disposed on or below the object portion, and does not necessarily mean disposed on the upper side of the object portion based on a gravitational direction.

In addition, unless explicitly described to the contrary, the word “comprise” and variations such as “comprises” or “comprising” will be understood to imply the inclusion of stated elements but not the exclusion of any other elements.

It will be understood that, although the terms “first,” “second,” “third” etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, “a first element,” “component,” “region,” “layer” or “section” discussed below could be termed a second element, component, region, layer or section without departing from the teachings herein.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms, including “at least one,” unless the content clearly indicates otherwise. “At least one” is not to be construed as limiting “a” or “an.” “Or” means “and/or.” As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

Furthermore, relative terms, such as “lower” or “bottom” and “upper” or “top,” may be used herein to describe one element's relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. The exemplary term “lower,” can therefore, encompasses both an orientation of “lower” and “upper,” depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The exemplary terms “below” or “beneath” can, therefore, encompass both an orientation of above and below.

Throughout this specification, a plan view means a view when observing a surface parallel to two directions (e.g., a first direction DR1 and a second direction DR2) crossing each other, and a cross-sectional view means a view when observing a surface cut in a direction (e.g., a third direction) perpendicular to the surface parallel to the first direction DR1 and the second direction DR2. Also, to overlap two constituent elements means that the two constituent elements are overlapped in the third direction (e.g., a direction perpendicular to an upper surface of the substrate) unless stated otherwise.

First, a structure of a display device according to an embodiment of the present invention will be described with reference to FIG. 1 to FIG. 4 .

FIG. 1 illustrates a plan view of a display device according to an embodiment of the present invention, FIG. 2 and FIG. 3 respectively illustrate a plan view of a display part of a pixel in a portion of a display area of a display device according to an embodiment of the present invention, and FIG. 4 illustrates a cross-sectional view of a display device according to an embodiment of the present invention.

Referring to FIG. 1 to FIG. 3 , a display panel 1000 included in a display device according to an embodiment includes a display area DA that may display an image, and a peripheral area PA disposed around the display area DA.

The display area DA may include a first display area DA1 and a second display area DA2. The second display area DA2 may have a smaller area than the first display area DA1. The first display area DA1 may be disposed between the second display area DA2 and the peripheral area PA in a second direction DR2. That is, the second display area DA2 may be spaced apart from the peripheral area PA in the second direction DR2. Specifically, the first display area DA1 may be disposed between the second display area DA2 and a lower peripheral area PA in a plan view, and the first display area DA1 may also be disposed between the second display area DA2 and an upper peripheral area PA in a plan view, referring to FIG. 1 .

FIG. 1 illustrates that the second display area DA2 is substantially circular, but the present invention is not limited thereto, and the second display area DA2 may have various shapes such as a polygonal shape in another exemplary embodiment.

The first display area DA1 may include a plurality of pixels PX. Each pixel PX may include a pixel circuit part including at least one transistor, and a display part in which a pixel electrode connected to the pixel circuit part is disposed and that may emit light.

FIG. 2 exemplarily illustrates display parts PB, PR, and PG included in the plurality of pixels PX disposed in the first display area DA1. For example, the display part PB may emit blue light, the display part PR may emit red light, and the display part PG may emit green light. The colors represented by the display parts PB, PR, and PG are not limited thereto, and may be various combinations of basic colors in another exemplary embodiment. That is, the display device may display images of various colors with a combination of different primary colors represented by the plurality of display parts PB, PR, and PG.

The second display area DA2 may include at least one pixel PX and at least one light-transmitting portion LTA. Referring to FIG. 3 , the arrangement of the pixels PX of the second display area DA2 in an area excluding the light-transmitting portion LTA may be the same or similar to that of the pixels PX of the first display area DA1. In some embodiments, the pixel arrangement of the second display area DA2 and the pixel arrangement of the first display area DA1 may be different. For example, the second display area DA2 may have a pixel arrangement structure of each RGB stripe type, while the first display area DA1 may have a pentile structure of pixel arrangement as shown in FIG. 2 . In the RGB stripe type of pixel arrangement structure, the display part of each pixel PX may have a substantially rectangular shape, and the pixels PX displaying the same color may be arranged in each pixel column, while pixel columns displaying different colors may be alternately arranged in a pixel row direction.

The pixel PX is not disposed in the light-transmitting portion LTA. Light may pass through the display panel 1000 in a third direction DR3 through the light-transmitting portion LTA. FIG. 3 illustrates that only two light-transmitting portions LTA are disposed in the second display area DA2, but the arrangement and the number of light-transmitting portions LTA are not limited thereto. For example, the plurality of light-transmitting portions LTA may be arranged substantially in a matrix form in the second display area DA2. In this case, the pixel PX may be disposed between adjacent light-transmitting portions LTA.

A circuit part, a signal line, a voltage line, and a pad part may be disposed in the peripheral area PA. In FIG. 1 , a driving circuit part 500 may be disposed in the lower peripheral area PA in a plan view. The driving circuit part 500 may have various forms such as at least one driving circuit chip, a flexible printed circuit film, and a printed circuit board.

A buffer layer 111 may be disposed on the substrate 110. The buffer layer 111 may be omitted.

An active layer 130 may be disposed on the buffer layer 111. The active layer 130 may include semiconductor materials such as polycrystalline silicon and an oxide semiconductor. The active layer 130 may include areas having different carrier concentrations from each other.

An insulating layer 141 may be disposed on the active layer 130, and a first conductive layer 150 a may be disposed on the insulating layer 141.

An insulating layer 142 may be disposed on the first conductive layer 150 a, and a second conductive layer 150 b may be disposed on the insulating layer 142.

An insulating layer 143 may be disposed on the second conductive layer 150 b, and a third conductive layer 170 a may be disposed on the insulating layer 143. An insulating layer 144 may be disposed on the third conductive layer 170 a, and a fourth conductive layer 170 b may be disposed on the insulating layer 144.

At least one of the first, second, third, and fourth conductive layers 150 a, 150 b, 170 a, and 170 b may include at least one of copper (Cu), aluminum (Al), magnesium (Mg), silver (Ag), gold (Au), platinum (Pt), palladium (Pd), nickel (Ni), neodymium (Nd), iridium (Ir), molybdenum (Mo), tungsten (W), titanium (Ti), chromium (Cr), tantalum (Ta), and an alloy thereof, but the invention is not limited thereto.

The first conductive layer 150 a, the second conductive layer 150 b, the third conductive layer 170 a, and the fourth conductive layer 170 b may be patterned and electrically connected to each other to form the pixel circuit part of the pixel PX.

An insulating layer 145 may be disposed on the fourth conductive layer 170 b, and a pixel electrode 191 may be disposed on the insulating layer 145.

At least one of the buffer layer 111, the insulating layer 141, the insulating layer 142, the insulating layer 143, the insulating layer 144, and the insulating layer 145 includes an inorganic insulating material such as a silicon nitride (SiNx) or a silicon oxide (SiOx), and/or an organic insulating material. Particularly, the insulating layer 145 may include an organic insulating material such as a polyacrylic resin or a polyimide resin, and an upper surface of the insulating layer 145 may be substantially flat.

An insulating layer 350 may be disposed on the insulating layer 145 and the pixel electrode 191. The insulating layer 350 is also referred to as a pixel defining layer. The insulating layer 350 may define an opening provided on the pixel electrode 191. The insulating layer 350 may include a pigment such as carbon black.

A light emitting layer 370 may be disposed on the pixel electrode 191. The light emitting layer 370 may include a portion disposed in the opening defined by the insulating layer 350.

The pixel electrode 191, the light emitting layer 370, and the common electrode 270 may together form a light emitting diode ED. The display part of the pixel PX may include the light emitting diode ED.

Here, the case in which the display panel 1000 is a light emitting display panel is described as an example, but the structure of the display panel 1000 is not limited thereto. For example, the display panel 1000 may be a liquid crystal display panel, an electrophoretic display panel, or an electrowetting display panel. In addition, the display panel 1000 may be one of various display panels such as a micro LED display panel, a quantum dot light emitting diode (“QLED”) display panel, and a quantum dot organic light emitting diode (“QD-OLED”) display panel.

An encapsulation layer for protecting the light emitting diode ED may be further disposed on the common electrode 270. The encapsulation layer may include an inorganic layer and an organic layer that are alternately stacked. In some embodiments, the encapsulation layer may include a substrate. The substrate 110 and the substrate of the encapsulation layer may include glass. In this case, the substrate 110 and the encapsulation layer may be bonded to each other through a sealant therebetween, and thus a gap between the encapsulation layer and the substrate 110 may be sealed.

Referring to FIG. 4 , the light-transmitting portion LTA may not include the configuration of the pixel PX described above, that is, the pixel circuit part and the display part. A layer through which light is not transmitted well, such as the first conductive layer 150 a, the second conductive layer 150 b, the third conductive layer 170 a, and the fourth conductive layer 170 b, may not be disposed in the light-transmitting portion LTA. FIG. 4 illustrates an example in which only the buffer layer 111 is disposed in the light-transmitting portion LTA, but the present invention is not limited thereto. In another exemplary embodiment, at least some of the other insulating layers 141, 142, 143, 144, 145, and 350 may remain without being eliminated. Unlike the example of FIG. 4 , the buffer layer 111 may also be eliminated from the light-transmitting portion LTA in still another exemplary embodiment.

The display area DA may include a plurality of data lines 171. Each data line 171 may substantially extend in the second direction DR2 in the display area DA. The data line 171 may be extended to the lower peripheral area PA in a plan view and be electrically connected to the driving circuit part 500 to receive a data signal.

Each data line 171 may be electrically connected to a transistor of the pixel circuit part adjacent thereto to transmit a data signal to the pixel circuit part.

Extension lines of each of the first portion 171 b 1 and the second portion 171 b 2 corresponding to each other may be disposed on the same straight line.

As shown in FIG. 5 , at least one of the first portion 171 b 1 and the second portion 171 b 2 of the second data line 171 b may include a portion extending to the inside of the second display area DA2. The light-transmitting portion LTA may be disposed between the first portion 171 b 1 and the second portion 171 b 2 of the second data line 171 b. That is, the first portion 171 b 1 and the second portion 171 b 2 of the second data line 171 b may be spaced apart with the light-transmitting portion LTA therebetween.

The first portion 171 b 1 and the second portion 171 b 2 of the second data line 171 b may be disposed at the same conductive layer on the substrate 110 described above, and may include the same material. For example, the first portion 171 b 1 and the second portion 171 b 2 of the second data line 171 b may be disposed at the third conductive layer 170 a of the embodiment illustrated in FIG. 4 described above.

The pattern portion 182 may include a bypass portion DTP that is disposed between the pattern portion 181 and the second display area DA2 and that bypasses (i.e., detours around) a periphery of the second display area DA2 in a plan view.

In FIG. 6 , the pattern portion 182 may extend in the lower peripheral area PA in a plan view to be electrically connected to the first portion 171 b 1 of the second data line 171 b through the opening 46, and may also extend in the upper peripheral area PA in a plan view to be electrically connected to the second portion 171 b 2 of the second data line 171 b through the opening 45. One end of the pattern portion 182 may be electrically connected to the first portion 171 b 1 of the second data line 171 b, and the other end of the pattern portion 182 may be electrically connected to the second portion 171 b 2 of the second data line 171 b.

The pattern portion 183 may include a vertical portion 183 a substantially extending in the second direction DR2 and a horizontal portion 183 b substantially extending in the first direction DR1. The vertical portion 183 a and the horizontal portion 183 b may be physically and electrically connected to each other, and may together receive a constant voltage.

The pattern portion 182 and the pattern portion 183 adjacent to each other are spaced apart from each other with the separation portions 80 and 81 therebetween, and are electrically insulated from each other.

The pattern portion 183 may not be disposed in the second display area DA2.

The pattern portion 181, the pattern portion 182, and the pattern portion 183 of the conductive pattern 180 may be disposed at the same conductive layer on the substrate 110 described above, and may include the same material. For example, the conductive pattern 180 may be disposed at the fourth conductive layer 170 b of the embodiment shown in FIG. 4 described above.

FIG. 7 illustrates the first portion 171 b 1 and the second portion 171 b 2 of the second data line 171 b illustrated in FIG. 5 together with a portion of the pattern portion 182 illustrated in FIG. 6 . In the pattern portion 182, the horizontal portion 182 b that extends from only one vertical portion 182 a and having one end ending at the separation portion 80 is omitted in FIG. 7 .

The pattern portion 182 may be electrically connected to the second portion 171 b 2 and the first portion 171 b 1 of the second data line 171 b through respective openings 45 and 46.

The first portion 171 b 1 of the second data line 171 b may receive a data signal from the driving circuit part 500, and it may transmit the data signal to a pixel of the first display area DA1 disposed at the lower side of the second display area DA2 in a plan view in FIG. 7 and to a pixel disposed at the lower side of the light-transmitting portion LTA in a plan view among pixels disposed in the second display area DA2.

In FIG. 7 , the second portion 171 b 2 of the second data line 171 b is disposed in the first display area DA1 disposed at the upper side of the second display area DA2 in a plan view, but the second portion 171 b 2 is spaced apart from the first portion 171 b 1 with the light-transmitting portion LTA therebetween. Thus, the second portion 171 b 2 may not directly receive the data signal from the first portion 171 b 1.

The pattern portion 182 according to the present embodiment may be electrically connected to the first portion 171 b 1 of the second data line 171 b in the lower peripheral area PA in a plan view to transmit a data signal, and it may be electrically connected to the second portion 171 b 2 of the second data line 171 b in the upper peripheral area PA in a plan view through the bypass portion DTP of the pattern portion 182. Accordingly, the second portion 171 b 2 of the second data line 171 b may receive a data signal from the first portion 171 b 1 of the second data line 171 b or the driving circuit part 500 through the pattern portion 182. Therefore, the data signal may be transmitted to the pixel circuit part of the pixels in the first display area DA1 and the second display area DA2 connected to the second portion 171 b 2 of the second data line 171 b.

When the data line is bypassed around the light-transmitting portion LTA in the second display area DA2, an area of the light-transmitting portion LTA may be reduced by the data lines densely disposed in the second display area DA2. Since a portion in which a large number of data lines are densely disposed in a small area occurs, an unwanted change of the data signal may be caused due to coupling between the data lines. However, according to the embodiment of the present invention, since there is no such problem, a sufficient area of the light-transmitting portion LTA can be secured, and since the data lines do not need to be densely disposed, influence due to coupling between the data lines may be reduced.

Referring to FIG. 6 , since the pattern portion 181 and the pattern portion 183 having a pattern similar to the pattern portion 182 are provided in the first display area DA1, it is possible to prevent only the pattern portion 182 from being partially viewed. In order to further prevent the conductive pattern 180 from being viewed from the outside, the insulating layer 350 disposed on the fourth conductive layer 170 b may include a pigment such as carbon black.

The pattern portion 181 and the pattern portion 183 may be applied with a constant voltage to not be floated. Accordingly, since it is possible to prevent a voltage of other adjacent conductors from being affected as potentials of the pattern portion 181 and the pattern portion 183 are changed by coupling with another conductor adjacent thereto, it is possible to prevent display characteristics of the display device from deteriorating.

In some embodiments of the present invention, the horizontal portions 181 b, 182 b, and 183 b of the conductive pattern 180 may be omitted.

Referring to FIG. 9 to FIG. 12 , the vertical portions 181 a and 182 a of the conductive pattern 180 overlap the driving voltage line 172 transmitting a driving voltage in a plan view, and may extend along the driving voltage line 172. The horizontal portions 181 b and 182 b of the conductive pattern 180 overlap the initializing voltage line 159 that transmits an initializing voltage in a plan view, and may extend along the initializing voltage line 159. Accordingly, the horizontal portions 181 b and 182 b and the vertical portions 181 a and 182 a of the conductive pattern 180 together with another conductive layer adjacent thereto form a parasitic capacitor, so that coupling that affects each other's signals or voltages may be prevented.

Particularly, the horizontal portion 182 b and the vertical portion 182 a of the pattern portion 182 that may transmit a data signal may change the data signal or affect a voltage or signal of the adjacent signal line, due to crosstalk with the adjacent signal line. However, according to the present embodiment, since the horizontal portion 182 b and the vertical portion 182 a of the pattern portion 182 overlap the driving voltage line 172 or the initializing voltage line 159 transmitting a constant voltage, an electric field may be shielded, thereby preventing a parasitic capacitance from occurring between them and surrounding signal lines.

The pattern portion 181 and the pattern portion 183 of the conductive pattern 180 may be electrically connected to a voltage line transmitting a driving voltage in the peripheral area PA. Accordingly, as described above, since it is possible to prevent voltage of other adjacent conductors from being affected as potentials of the pattern portion 181 and the pattern portion 183 are changed by coupling with another conductor adjacent thereto, it is possible to prevent display characteristics of the display device from deteriorating.

The insulating layer 145 may be disposed on the fourth conductive layer. The insulating layers 144 and 145 may define an opening 89 provided on the connecting member 179.

As described above, the pixel electrode 191, the light emitting layer 370, and the common electrode 270 may be sequentially disposed on the insulating layer 145. The pixel electrode 191, the light emitting layer 370, and the common electrode 270 may together form the light emitting diode ED.

In a plan view, the plurality of pixel electrodes 191 may be arranged in, for example, a pentile matrix structure as shown in FIG. 2 and FIG. 3 described above.

Hereinafter, a display device according to another embodiment of the present invention will be described with reference to FIG. 13 to FIG. 15 together with the drawings described above.

FIG. 13 , FIGS. 14, and 15 respectively illustrate a plan view of a display device according to an embodiment of the present invention.

The display device according to the present embodiment is mostly the same as the display device according to the above-described embodiment, for example, the embodiments illustrated in FIG. 5 and FIG. 6 . Therefore, differences from the above-described embodiment will be mainly described.

Unlike the previous embodiment, the first portion 171 b 1 of the second data line 171 b may not be electrically connected to the second portion 171 b 2 of the second data line 171 b in the lower peripheral area PA in a plan view. Instead, the first portion 171 b 1 of the second data line 171 b of this embodiment may be electrically connected to the conductive pattern 180 through an opening 48 in the first display area DA1 around the lower side of the second display area DA2.

The second portion 171 b 2 of the second data line 171 b may be electrically connected to the conductive pattern 180 through an opening 47 in the first display area DA1 around the upper side of the second display area DA2. Alternatively, the second portion 171 b 2 of the second data line 171 b may be electrically connected to the conductive pattern 180 through an opening in the peripheral area PA.

Specifically, referring to FIG. 14 , the conductive pattern 180 according to the present embodiment may include the pattern portion 181 and a pattern portion 184.

The pattern portion 181 may include the vertical portion 181 a substantially extending in the second direction DR2 and the horizontal portion 181 b substantially extending in the first direction DR1 as in the above-described embodiment. The vertical portion 181 a and the horizontal portion 181 b may be physically and electrically connected to each other, and may together receive a constant voltage.

The pattern portion 181 may be spaced apart from the second display area DA2. The pattern portion 181 may also be disposed at the lower side of the second display area DA2 in a plan view.

The pattern portion 184 may include a vertical portion 184 a substantially extending in the second direction DR2 and a horizontal portion 184 b substantially extending in the first direction DR1. The vertical portion 184 a and the horizontal portion 184 b may be physically and electrically connected to each other.

Unlike the pattern portion 182 of the embodiment described above, the pattern portion 184 may be disposed only around the second display area DA2, and may include the bypass portion DTP that is disposed between the pattern portion 181 and the second display area DA2 and bypasses the periphery of the second display area DA2.

The pattern portion 181 and the pattern portion 184 adjacent to each other are spaced apart from each other with the separation portions 80 and 81 therebetween, and are electrically insulated from each other.

In this embodiment, a length of the pattern portion 184 in the second direction DR2 may be shorter than a length of the display area DA in the second direction DR2.

The pattern portion 184 may be electrically connected to the first portion 171 b 1 of the second data line 171 b through the opening 48 in the first display area DA1 around the lower side of the second display area DA2, and the pattern portion 184 may also extend to the upper peripheral area PA in a plan view to be electrically connected to the second portion 171 b 2 of the second data line 171 b through the opening 47. One end of the pattern portion 184 may be electrically connected to the first portion 171 b 1 of the second data line 171 b, and the other end of the pattern portion 184 may be electrically connected to the second portion 171 b 2 of the second data line 171 b.

FIG. 15 illustrates the first portion 171 b 1 and the second portion 171 b 2 of the second data line 171 b illustrated in FIG. 13 and a portion of the pattern portion 184 illustrated in FIG. 14 . In the pattern portion 184, the horizontal portion 184 b that extends only to the vertical portion 184 a and has one end ending at the separation portion 80 is omitted in FIG. 15 .

Referring to FIG. 15 , the bypass portion DTP of the pattern portion 184 may include one vertical portion 184 a adjacent to the second display area DA2, and a pair of horizontal portions 184 b extending from upper and lower ends of the vertical portion 184 a.

The first portion 171 b 1 of the second data line 171 b may be electrically connected to the pattern portion 184 through the opening 48 in the first display area DA1 around the lower side of the second display area DA2. The second portion 171 b 2 of the second data line 171 b may be electrically connected to the pattern portion 184 through the opening 47 in the first display area DA1 around the upper side of the second display area DA2.

The first portion 171 b 1 of the second data line 171 b may receive a data signal from the driving circuit part 500, and may transmit the data signal to the pixel of the first display area DA1 disposed at the lower side of the second display area DA2 in a plan view and to the pixel disposed at the lower side of the light-transmitting portion LTA in a plan view among the pixels disposed in the second display area DA2.

In FIG. 15 , the second portion 171 b 2 of the second data line 171 b is disposed in the first display area DA1 disposed at the upper side of the second display area DA2 in a plan view, but since the second portion 171 b 2 is spaced apart from the first portion 171 b 1 with the light-transmitting portion LTA therebetween, the second portion 171 b 2 cannot directly receive the data signal from the first portion 171 b 1.

The pattern portion 184 according to the present embodiment may be electrically connected to the first portion 171 b 1 of the second data line 171 b through the opening 48 in the first display area DA1 around the lower side of the second display area DA2 to transmit a data signal, The pattern portion 184 may be electrically connected to the second portion 171 b 2 of the second data line 171 b through the opening 47 in the first display area DA1 around the upper side of the second display area DA2 via the bypass portion DTP of the pattern portion 184. Accordingly, the second portion 171 b 2 of the second data line 171 b may receive a data signal from the first portion 171 b 1 of the second data line 171 b or the driving circuit part 500 through the pattern portion 184. Accordingly, the data signal may be transmitted to the pixel circuit parts of the first display area DA1 and the second display area DA2 connected to the second portion 171 b 2 of the second data line 171 b.

According to an embodiment, since it is not necessary to densely dispose the data lines and then bypass the second display area DA2, a sufficient area of the light-transmitting portion LTA may be secured, and influence due to coupling between the data lines may be reduced.

Referring to FIG. 14 , since the pattern portion 181 similar to the pattern portion 184 is provided in the first display area DA1, it is possible to prevent only the pattern portion 184 from being partially viewed.

The pattern portion 181 may be applied with a constant voltage not to be floating. Accordingly, since it is possible to prevent a voltage of another adjacent conductor from being affected as a potential of the pattern portion 181 is changed by coupling with still another conductor adjacent to the pattern portion 181, it is possible to prevent display characteristics of the display device from deteriorating.

While this invention has been described in connection with what is presently considered to be practical embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
